BUBBLE-BLOWER.

SPECIFICATION forming part of Letters Patent No. 608,860, dated August 9, 1898. Application filed June 18, 1897. Serial No. 641,373. (No model-l To aZZ whom it may concern.-

Be it known that I, PETER D. HORTON, a citizen of the United States, residing at Oakland, in the county of Alameda and State of Cali- 5 fornia, have invented a new and useful Improvement in Bubble-Blowers, of which the following is a specification.

My invention relates especially to a novel device for blowing bubbles; and it has for its object the production of a bubble-blower capable of producing a variety of bubbles of different sizes.

To attain this end my invention consists in a hollow stem or tube closed at one end, a

[ short conical tube fixed in said stem near the closed end in upright position at right angles to the stem and having a shallow flaring head, and an aperture or opening in the stem provided with a slidable valve, as hereinafter fully described.

The following description explains at length the construction of the said parts and their combination together, reference being had to the accompanying drawings, which form part 2 5 of this specification.

Figure l of the said drawings is a view in perspective of my bubble-blower. Fig. 2 is a side view, partly in section, to show the short conical tube and its connection with the stem.

0 Fig. 3 is a plan or top view.

A represents the hollow stem or tube, and a the plug closing the outer end, so asto render it air-tight.

Bis the short conical tube,which is inserted in upright position tightly in the stem, with its lower end 13 fitting into the aperture and extending nearly to the bottom of the bore of the stem. Between this end 6 and the end a an open space or chamber a is partly separated or out off from the passage in the stem. The outer end of this upright tube terminates in a flaring head I) of circular shape, somewhat resembling a very shallow cup b As thus constructed the bubbles are formed on this head b by the air forced into the stem from the open end by the mouth of the blower, the head b being previously dipped into the soapy solution or a drop of the solution being deposited in the hollow of the disk.

The sizes of the bubbles produced are va- 5o 'ried by changing the size of the aperture C,

which is located on the upper side of the stem between the mouthpiece of the stem and the upright tube 13. A valve formed of a collar O fitted to slide on the stem and cover the aperture 0, forms a valve by which the size of the said outlet 0 is readily enlarged or reduced. Through the aperture C thus provided the air escapes in a jet of greater or less volume and force and is directed against the bubble.

If the valve be set to produce a fine jet or stream, the bubble will grow to a considerable size before the jet will impinge and strike it with sufficient force to detach it from the tube B, as the orifice C is so arranged as to direct the jet at an angular elevation above the horizontal to strike the bubble. When the orifice'C is left of full size, the jet will strike quite close down to the rim of the head b and thereby dislodge the bubble soon after it begins to form. This adjustment will cause a volley of small bubbles to be rapidly formed and projected into the surrounding air, and by reducing the size of the aperture C the bubbles will expand until they become of considerable size before they are blown off by the jet.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is

A bubble-blower consisting of a hollow stem or tube having a fixed head in one end; a conical tube fixed in said stem in upright position near the closed end, said upright tube having a flaring head with a shallow cavity in the center; an aperture in the upper side of the stem in proximity to the upright tube; and an adjustable valve for regulating the size of said aperture, as set forth.

In testimony that I claim the foregoing I have hereunto set my hand and seal.
